Comparison
APIMock vs Postman mock servers
Choose APIMock when you just need a mock: a hosted URL with stateful CRUD data, conditional responses and fault injection, shared with your team for free. Choose Postman if your API already lives in Postman collections and you want mocks next to your tests, monitors and docs, or want to script mock behaviour in JavaScript.

Disclosure: we build APIMock. Every Postman fact on this page comes from Postman's pricing page or docs as of October 20, 2026, linked under Sources. Plans change, so check their page before you decide.
Feature comparison
| APIMock | Postman | |
|---|---|---|
| Price | Free. There are no paid plans. | Free plan for 1 user; Solo $9/month and Team $19 per user/month, billed annually; Enterprise on request. |
| Free request allowance | 50,000 per month per workspace. | No mock-call limit is stated on Postman's pricing page. |
| Request history | 7 days of headers, query and timing; body previews when capture is on. | Mock call log with request and response headers and body; retention not stated. |
| How long free mocks last | Mocks stay until you delete them. | No expiry is stated in Postman's mock server docs. |
| Stateful CRUD data | Resources with pagination, filtering, sorting and seed data. | Collection mocks return saved examples. JavaScript mocks can keep state; hosting them as mock servers needs Solo or above. |
| Different responses per request | Response variants matched on headers, query, path params, cookies or body fields, chosen by weight, or forced with a header. | Saved examples scored on method, path and query, optionally headers and body; force one with an x-mock-response-name, -id or -code header. |
| OpenAPI import | Import from a file or URL, with optional request validation; extra examples become response variants. | Imports OpenAPI as a collection or a spec; mock servers serve a collection's saved examples. |
| Failure testing | Fault injection: error statuses, latency and broken payloads, per request header or by rule. | Delay from the mock settings or an x-mock-response-delay header (up to 180 seconds); pick an error example by status code. |
| Protocols | REST over HTTPS. | Mock servers support collections with HTTP requests only. |
| Proxy and local tunnel | Not offered. | The desktop app's proxy captures HTTP traffic into history or a collection. |
| Teams | Up to 3 workspaces with members and roles, free. | The free plan is 1 user; team collaboration from the $19 Team plan. |
| MCP server for AI agents | Yes, free, with OAuth sign-in or an access token. | Yes: Postman's MCP server, remote with OAuth or local with an API key, has tools to create and update mocks. |
Choose APIMock when
- You want teammates on the same mocks without paying per user.
- Your frontend needs hosted data that persists across create, update and delete calls, without writing handler code.
- You want to inject errors, latency and broken payloads by rule, without saving an example for each.
- You want a mock without building and maintaining a Postman collection.
- You want each request's headers and timing kept for 7 days.
Choose Postman when
- Your API already lives in Postman collections and you want mocks next to your tests, monitors and docs.
- You want to write mock behaviour in JavaScript.
- You want to capture real app traffic into a collection with the desktop proxy.
